Technological TerrorFor the discussion of items of technology such as motors, controllers, motion sensors, audio boards etc. Also to discuss how to hack commercial electronic props.

Now I'm tempted to intentionally fry some electronics just so I can be part of the blue smoke club. I once blasted an LED in half by omitting the resistor, and the top half of the LED flew a few feet. But I didn't see any blue smoke. Either way, Homey, I agree it's good to have some on hand for future efforts!

Just remember not to touch the chip after it lets out the blue smoke - there is a Picaxe 08M out there somewhere with my fingerprint permanently etched to its surface. allow it to cool down before you do anything with it.

Build it, if it works leave it alone if does not try something else

Blue Smoke is very hard to see, especially when you're working on Halloween props. Like a poltergeist, it appears, does it's damage and dissappears very quickly leaving behind a faint unmistakable odor.

It works beyond the speed of light and can sneak out without any notice.

And to think Adafruit is giving away badges for people that let it loose:

Oh, and then there was the time when I was first learning all this stuff. I had eight LEDs hooked up to an EFX Prop-2...and in my excitement, forgot the resistors. I had demo code that would turn on the LEDs one after the other (you guys can see what's coming) and when I powered it on, I watched in surprise as the LEDs burned out and made a nice "Pop", one after the other, right down the row. I managed to stop it before they all went!

That's called running in monostable mode or "One Shot"

I learned to be careful when I first started building electroncs
at age 9. My grandfather passed away and left me all his Radio Tv repair
business tools and parts includinge his soldering iron. Very much like this one:

It made a lot more than Blue Smoke appear....
I had burnt fingers.....good thing Surface Mount stuff wasn't around yet
